21
An exercise in moral complexity, 21 is based on Ben Mezrich's book Bringing Down the House: The Inside Story of Six M.I.T. Students Who Took Vegas for Millions. Jim Sturgess (Across the Universe) plays brilliant, blue-collar scholar Ben Campbell, whose doubts that he'll win a scholarship to Harvard Medical School compel him to join a secret, M.I.T. gang of math whiz kids. Under the silky but chilling command of a math professor (Kevin Spacey), Jim and the others master card counting, i.e., the statistical analysis of cards dealt in blackjack games.
